PATENT oEEIcE.

WMQLEwIs AND WM.`H. LEWIs, E NEW YORK, N. Y.

FASTENING rEDEsTALs To COLUMNS.

i Specification of Letters Patent No. 8,181, datedJune 24, 1851;

To all-whom z'timay concern.'

Be it known that we, WILLIAM LEWIS and WILLIAM I-I. LEWIS, of the city, county, and State of New York, manufacturers of daguerreotype apparatus, `have invented, made, and applied to use a new and useful Improvement y in the Means of Attaching the :Pedestal` to the` Column carryin a Table-Top, Stool,` or other .Useful Article, and that the said improvement and the construction and application of the same are fully and substantially set forth in the following description, and in the` drawing anneXed tc and making part of this specification, wherein`n "Figure l, is a `plan beneath or of theA lower side of the pedestal which `is here shown as of cast iron, made three sided, but maybe of any suitable shape or substance and shows the parts that receive the column Fig. 2, plan beneath or of the lower end of the column, showingthe parts that attach it to the pedestal. Fig. 3, is asimilar plan showing the column andpedestal attached together. Fig. 4, is a section of the pedestal. Fig. 5, is a side elevation of the lower end of the column, and Fig. 6,

is a plan similar to Fig. 3, but with the addition of a locking piece to prevent the column turning in the pedestal; the like marks of reference applyto the same parts in all` the figures.`

a, is a pedestal supported on balls or y other feet 1.

2, is a circular hole in the center on one side of which is a notch 3, formed with a curved end, and 4 is a notch on the opposite side of the hole 2, formed` square; and around the hole 2, is an inclined flanch 5, on one side and on the other is a similar inclined `flanch 6, shownin the section Fig. 4, and on the upper side of the pedestal is a seat 7, to receive a column b, see Fig. 5. This is formed either "solid or hollow and on the lower end is a cylindrical piece c, with a square lug s, and a round ended lug 9 on the opposite side. ,y

The attachment of the pedestaland column is to bemade by `entering the piece c,

into and through the hole 2, the `lug 8 passing `through Ithefnotch 4 and the lugQ` passing through the notch 3 and giving the column about`onethird a revolution in the direction, ofthe arrow, Fig. 3, the lug 8 sliding over the incline 6 and the lug 9 over the incline, drawing the column @tight ontothesleat 7 making atightattachment.

where this is applied, where the use tendsv to twist? the column, asin a piano stool, the

column might turn and disconnect the I parts. To prevent this we form a locking pieced, to set over the piece c, with notches to take the lugs 8 and 9,and with a curved slot l() setting over a fixed stud 1l, and a binding nut `l2, secures the lockpiece and prevents the` column from turningso as to disconnect, or this nut 12 may be made as a thumb screw to pass through the slot 10, into a fixed nut beneath.

We do not intend to limit the use of this i tometallic pedestals and columns as the partslmay be madeof metal, and attached.` `to wood pedestals and columns, although we prefer the whole to be made of metal together, neither do we intend to `limit the use of this attachment to pedestals and col-` umns for tablesor piano stools, as the same may be used as the base for a daguerreotype camera, or head rest, or for any other useful purpose. i. And the column is herein shown as hollow so as to receive the screw of the piano stool, or may receive arod to carry any other article, with a screw `to hold the same at any height to which it may be raised. 1

Therefore what we claim as new and of our own invention is- The application of the piece c, and different shaped lugs `8, and 9, on the end ofV the column to enter the hole 2, and notches 3V and 4 so that on turning the column the lugs 8 and 9, take the inclined seats 5 and `6,\to attach the column to the pedestal in combination with the locking piece d, to prevent the column turning substantially as described and shown.

In witness whereof we have hereto set oursignatures this thirteenth day of F eb` ruary fifty-one. l
